- Non-root user execution with security hardening
- Read-only filesystem with targeted writable volumes
- Resource limits (1GB RAM, 1 CPU) with health checks
- Multi-stage builds optimized for caching
- Zero-downtime deployment automation

🔍 Comprehensive Monitoring Stack:
- Prometheus metrics collection with custom rules
- Grafana dashboards for application visualization
- AlertManager with email notifications for critical events
- Fluentd centralized logging with retention policies
- Node Exporter + cAdvisor for system/container metrics
- Health check endpoint (/health) for container orchestration

📋 Production Deployment Ready:
- Complete deployment scripts with backup strategy
- Environment templates for secure configuration
- Performance monitoring and alerting rules
- Enterprise-grade security and observability

+
+## Quick Start
+
+### 1. Prerequisites
+
+- Docker Engine 20.10+
+- Docker Compose 2.0+
+- Linux server with at least 2GB RAM
+- Domain name with DNS pointing to your server
+
+### 2. Initial Setup
+
+```bash
+# Clone repository
+git clone <repository-url>
+cd LittleShop
+
+# Copy and configure environment
+cp .env.production.template .env
+nano .env  # Configure your secrets
+
+# Create required directories
+sudo mkdir -p /opt/littleshop/{data,uploads,logs,backups}
+sudo chown -R $USER:$USER /opt/littleshop
+```
+
+### 3. Deploy Application
+
+```bash
+# Deploy production application
+./deploy-production.sh
+
+# Deploy monitoring stack (optional)
+docker-compose -f docker-compose.monitoring.yml up -d
+```
+
+## Configuration Files
+
+### Environment Configuration
+
+The `.env` file contains all production secrets:
+
+```env
+# Required Configuration
+JWT_SECRET_KEY=your-super-secret-jwt-key-minimum-32-characters
+BTCPAY_SERVER_URL=https://your-btcpay-server.com
+BTCPAY_STORE_ID=your-store-id
+BTCPAY_API_KEY=your-api-key
+BTCPAY_WEBHOOK_SECRET=your-webhook-secret
+
+# Optional Configuration
+GRAFANA_ADMIN_PASSWORD=secure-grafana-password
+```
+
+### Docker Configurations
+
+| File | Purpose |
+|------|---------|
+| `Dockerfile` | Optimized production image with security hardening |
+| `docker-compose.prod.yml` | Production deployment with resource limits |
+| `docker-compose.monitoring.yml` | Monitoring and observability stack |
+
+## Security Features
+
+### Container Security
+
+- **Chiseled Ubuntu**: Minimal attack surface with distroless-like images
+- **Non-root user**: Application runs as unprivileged user
+- **Read-only filesystem**: Container filesystem is read-only except for specific volumes
+- **Resource limits**: Memory and CPU limits prevent resource exhaustion
+- **Security options**: `no-new-privileges` prevents privilege escalation
+
+### Network Security
+
+- **Internal networks**: Service-to-service communication on isolated networks
+- **TLS termination**: All traffic encrypted with Let's Encrypt certificates
+- **Security headers**: HSTS, XSS protection, content-type sniffing protection
+- **CORS policies**: Strict cross-origin resource sharing policies
+
+### Data Security
+
+- **Persistent volumes**: Data persisted outside containers
+- **Backup strategy**: Automated database backups before deployments
+- **Log retention**: Configurable log retention policies
+
+## Monitoring and Observability
+
+### Health Checks
+
+The application exposes health check endpoints:
+
+- `/health` - Application health status
+- `/health/ready` - Readiness probe for Kubernetes
+- `/health/live` - Liveness probe for container orchestration
+
+### Metrics Collection
+
+Prometheus collects metrics from:
+
+- **Application metrics**: Custom business metrics
+- **System metrics**: CPU, memory, disk, network via Node Exporter
+- **Container metrics**: Docker container statistics via cAdvisor
+- **Log metrics**: Log aggregation and error rates via Fluentd
+
+### Alerting
+
+AlertManager handles:
+
+- **Critical alerts**: Application down, database failures
+- **Warning alerts**: High resource usage, elevated error rates
+- **Notification channels**: Email, webhooks, Slack integration
+
+### Dashboards
+
+Grafana provides:
+
+- **Application dashboard**: Request rates, response times, error rates
+- **Infrastructure dashboard**: System resources, container health
+- **Business dashboard**: Orders, payments, user activity
+
+## Deployment Process
+
+### Zero-Downtime Deployment
+
+The `deploy-production.sh` script implements:
+
+1. **Health check** of existing container
+2. **Database backup** before deployment
+3. **Image building** with latest code
+4. **Rolling update** with health verification
+5. **Cleanup** of old images and containers
+
+### Rollback Strategy
+
+```bash
+# List available backups
+ls /opt/littleshop/backups/
+
+# Restore from backup
+cp /opt/littleshop/backups/littleshop-YYYYMMDD-HHMMSS.db /opt/littleshop/data/littleshop.db
+
+# Restart application
+docker-compose -f docker-compose.prod.yml restart
+```
+
+## Performance Optimization
+
+### Docker Optimizations
+
+- **Multi-stage builds**: Separate build and runtime stages
+- **Layer caching**: Optimized layer order for build cache efficiency
+- **Image size**: Minimal base images with only required dependencies
+- **Build context**: Optimized `.dockerignore` excludes unnecessary files
+
+### Application Optimizations
+
+- **ReadyToRun images**: Pre-compiled for faster startup
+- **Garbage collection**: Optimized GC settings for container environments
+- **Connection pooling**: Database connection pooling enabled
+- **Compression**: Response compression enabled
+
+### Resource Management
+
+```yaml
+deploy:
+  resources:
+    limits:
+      memory: 1G      # Maximum memory usage
+      cpus: '1.0'     # Maximum CPU cores
+    reservations:
+      memory: 512M    # Guaranteed memory
+      cpus: '0.5'     # Guaranteed CPU cores
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### Container Won't Start
+
+```bash
+# Check container logs
+docker-compose -f docker-compose.prod.yml logs littleshop
+
+# Check health status
+docker exec littleshop_prod curl -f http://localhost:8080/health
+```
+
+#### High Memory Usage
+
+```bash
+# Check resource usage
+docker stats littleshop_prod
+
+# Review memory configuration
+docker inspect littleshop_prod | grep -i memory
+```
+
+#### Database Issues
+
+```bash
+# Check database connectivity
+docker exec littleshop_prod sqlite3 /app/data/littleshop.db ".tables"
+
+# Restore from backup
+cp /opt/littleshop/backups/latest.db /opt/littleshop/data/littleshop.db
+```
+
+### Log Analysis
+
+```bash
+# Application logs
+docker-compose -f docker-compose.prod.yml logs -f littleshop
+
+# System logs
+journalctl -u docker -f
+
+# Aggregated logs (if monitoring stack deployed)
+docker exec littleshop_fluentd tail -f /fluentd/log/output/littleshop.*.log
+```
+
+## Maintenance
+
+### Regular Tasks
+
+1. **Update base images** monthly
+2. **Review security alerts** weekly
+3. **Clean up old logs** based on retention policy
+4. **Backup verification** monthly
+5. **Performance review** quarterly
+
+### Updates
+
+```bash
+# Update application
+git pull
+./deploy-production.sh
+
+# Update monitoring stack
+docker-compose -f docker-compose.monitoring.yml pull
+docker-compose -f docker-compose.monitoring.yml up -d
+```
+
+## Support
+
+For issues and questions:
+
+1. Check logs first: `docker-compose logs`
+2. Review monitoring dashboards
+3. Check health endpoints
+4. Review this documentation
+5. Contact system administrator
+
+---
+
+**Production Deployment Status**: ✅ Ready for production use with enterprise-grade monitoring and security.
